Detailed description of the invention
The technical scheme provided this utility model below in conjunction with Fig. 1～Fig. 3 illustrates in more detail.
The present embodiment is as a example by heat exchanger uses on air-conditioning.The blower fan of air-conditioning is approximately in body height direction
Portion, heat exchanger is normally at below blower fan, and the distance the most remote air quantity of blower fan is the least.Upstream, downstream with the landing direction of condensed water are
Reference, in the present embodiment, the first header 1 is in the upstream of the second header 3.
Seeing Fig. 1 and Fig. 2, this utility model embodiment one provides a kind of heat exchanger, collects including the first header 1, second
Flow tube 3 and heat exchanger tube 4.Upstream extremity and first header 1 of heat exchanger tube 4 connect, the downstream of heat exchanger tube 4 and the second header
3 connections；Wherein, adjacent two heat exchanger tubes 4 are smaller than the spacing in downstream end at upstream extremity.
Spacing at upstream extremity refers to adjacent two heat exchanger tubes 4 spacing near the first header 1, the spacing of downstream end
Refer to adjacent two heat exchanger tubes 4 spacing near the second header 3.
Specifically, along being from upstream to the direction in downstream, the spacing of adjacent two heat exchanger tubes 4 is gradual change.Adjacent two
The heat exchanger tube 4 spacing at upstream extremity is minimum, maximum in the spacing of downstream end.Following manner specifically can be used to realize:
Seeing Fig. 1, in the present embodiment, heat exchanger tube 4 is straight tube, along being from upstream to the direction in downstream, and adjacent two heat exchange
The spacing of pipe 4 is gradual change.Adjacent two heat exchanger tubes 4 are basic to be arranged in "eight" shape, is from upstream to downstream span and becomes larger.
In the present embodiment first header 1 and the structure of second header 3 is described below.
In the present embodiment, the structure of each heat exchanger tube 4 is identical, i.e. the structure of each cross section of heat exchanger tube 4 is identical, is all oblate
Shape.
Alternatively, in the present embodiment, the first header 1 and the second header 3 are all annular, and the first header 1
Girth is than all length of the second header 3.
Annular can be annular, or oval ring, or rectangular-shaped annular etc..
No matter the first header 1 be annular or straight tube referred to hereafter, the second header 3 for annular or hereinafter
The straight tube mentioned, the first header 1 is designed with several the first through hole connected with heat exchanger tube 4, the second header 3 is designed with
Several the second through holes connected with heat exchanger tube 4.First through hole and the second through hole one_to_one corresponding and quantity are equal, and every pair first leads to
A heat exchanger tube 4 it is provided with between hole, the second through hole.Each first through hole can spaced set, each second through hole can spaced set.
Further, the straight line connecting the center of the first header 1 and the center of the second header 3 is perpendicular to the first afflux
The plane at pipe 1 place.Using this structure, the structure of heat exchanger is that upper end is big, lower end is little, more firm during placement, is more easy to peace
Dress.
The set-up mode of fin 2 is described below.It is provided with along heat exchanger tube 4 length extension side between adjacent two heat exchanger tubes 4
To fin 2；At the upstream extremity of fin 2 more intensive than downstream end.
The heat exchange efficiency of heat exchanger is relevant with air quantity and heat exchange area, heat exchange efficiency=air quantity/heat exchange area.Air quantity is big,
The little then heat exchange efficiency of heat exchange area is high.One end near the first header 1 of fin 2 is upstream extremity, and fin 2 is near the second afflux
One end of pipe 3 is downstream.Fin 2 uses said structure, in the region that bottom air quantity is little, and fin 2 sparse；At top air quantity
Big region, fin 2 is intensive, and the heat exchange efficiency of whole heat exchanger is more uniform, and is conducive to discharging condensed water and reducing sky
Flow of air resistance.
Seeing Fig. 1, the fin 2 between adjacent two heat exchanger tubes 4 is laciniation；Along being from upstream to downstream
Direction, wave height h of fin 2 is progressively longer or stairstepping is elongated.Owing to the spacing at the upstream extremity of adjacent two heat exchanger tubes 4 is little
In the spacing of downstream end, correspondingly, along being from upstream to the direction in downstream, the wave height of fin 2 is progressively longer or stairstepping
Elongated, with the structure of corresponding heat exchanger tube 4 so that fin 2 is fully contacted with heat exchanger tube 4, thus ensures heat exchange efficiency.
Seeing Fig. 3, the technical scheme of this utility model embodiment two has following with the technical scheme of above-described embodiment one
Different: along being from upstream to the direction in downstream, the spacing of adjacent two heat exchanger tubes 4 is steps change.
Heat exchanger tube 4 can be bend pipe, and along being from upstream to the direction in downstream, the spacing of adjacent two heat exchanger tubes 4 is steps
Change, as shown in Figure 3.On first header 1, the spacing between adjacent two the first through holes is little, adjacent on the second header 3
Spacing between two the second through holes is big, and heat exchanger tube 4 is bend pipe, and upstream extremity and the first header 1 connect, downstream and the second collection
Flow tube 3 connects, and at the stairstepping sudden change of heat exchanger tube 4, the spacing between adjacent two heat exchanger tubes 4 also occurs stairstepping to change.
It should be noted that Fig. 3 illustrates that the situation of each heat exchanger tube 4 only one of which sudden change ladder, actual can also set as required
Put two or more sudden change ladder.
In the present embodiment, the first header 1 and the second header 3 are all straight tube, and the length ratio second of the first header 1
The length of header 3 is short.
First header the 1, second header 3, heat exchanger tube 4 substantially form trapezium structure.First header 1 is provided with several
The first through hole connected with heat exchanger tube 4, the second header 3 is provided with several the second through hole connected with heat exchanger tube 4.First through hole
Equal with the second through hole one_to_one corresponding and quantity, it is provided with a heat exchanger tube 4 between every pair of the first through hole, the second through hole.
Technique scheme, due to the spacing being smaller than downstream end at the upstream extremity of adjacent two heat exchanger tubes,
During condensed water is discharged, more down migration, the spacing between heat exchanger tube is the biggest, and condensed water does not haves water blocking phenomenon, makes
Obtain air can circulate easily, will not occur that water blocking reduces air quantity because of condensed water, it is ensured that system reliability and heat exchange effect
Rate.
